Phantom 3 Professional (Water Damaged)

I have a phantom 3 professional landed softly in the ocean. Got it out in about 45 seconds and it was still running.

Rinsed it thoroughly in distilled water and rice/dried it out and it turns on but has ECC errors. DJI GO app connects and can move the gimbal and see through it (although its also seemly in need of maintenance).

The battery is no good.

I can part anything out if anyone knows what to do with the air craft/ gimbal.
